OnCancelledEventTrigger

@Serializable
@SerialName(value = "OnCancelled")
object OnCancelledEventTrigger : EventTrigger

Fires when the user dismisses/cancels an interactive platform flow without completing it — OpenFilePicker/TakePicture/GetImageFromGallery (no choice made) and DownloadFile (the platform save dialog cancelled), instead of the matching onFailure().
